An SD card might work fine if it is mounted properly. The slot found on a Raspberry Pi would not at all be sufficient.

If it were held in and held against some robust contact pins it likely would be fine, even under automotive conditions. There are SIM card slots that are used on heavy vehicle computers and controllers (the ones that run the engine and so on) that are robust enough to hold a SIM card in place for years of excessive daily vibration.




Whenever I drop my phone I see the "SimProcessor" service spinning up...

I suspect that designing reliable spring contacts isn't as easy as it seems...


Yeah, phones aren't designed to have robust SIM slots, they're designed to be thin, so they use very low profile SIM cradles that are not robust to impact.

The trade-offs for a high vibration environment are very different.
